Subject: reenabling disabled ata links from the command line
Date: Sun, 13 Jun 2010 11:06:00 +0200	[thread overview]
Message-ID: <20100613090600.GA31086@basil.fritz.box> (raw)

Hi,

I recently found myself in a situation where I had to recover some data
from a SATA disk with broken sata connector.

In the end I had to reboot quite often to get the sata hardware/driver
to retry to reconnect a link when I fixed the connector in a slightly
different angle.

On the first connect the hardware detected it by itself,
but the problem was that once it lost the link the ata interface
was disabled and only a reset could fix that, I think(?)

So I was wondering is there a way to reenable a link that has been
disabled to try again?

I presume a module reload would do it, but that's not practical when your
root fs is on another SATA port.

Should something like this be implemented?

Thanks,
-Andi
